  1. 1. Truck Tyre Vibration Behaviour. Measurements and High Frequency Modelling

    Author : Penka Dinkova; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; vibration response; mobility measurements; truck tyre; heavy vehicle; tyre-road noise; tyre; driving point mobility; transfer mobility; tire; vibration prediction; model;

    Abstract : To facilitate tyre-road noise prediction, a computationally efficient high frequency tyre model is needed. Such models are always a compromise between the desired accuracy and the need for simplicity. In addition the accuracy of models is often limited by the quality of the input data available.

  2. 2. High Frequency Tyre Vibrations

    Author : Patrik Andersson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; local deformation; adhesion; tyre model; air pumping; parameter study; tyre road noise; tyre road prediction models; tyre noise;

    Abstract : High frequency (above 1 kHz) noise generation from the tyre/road interaction is still not fully understood and accurately modelled.Two noise generation mechanisms previously suggested in the literature are reviewed: air pumping and noise generation cased by adhesive effects between the tyre tread and road surface.

  3. 3. Excitation of Tyre Vibrations due to Tyre/Road Interaction

    Author : Frédéric Wullens; Chalmers University of Technology; []
    Keywords : tyre road interaction; tyre road noise; tyre structure modelling; contact modelling;

    Abstract : Tyre/road noise is the main contributor to road traffic noise at speeds above 40 km/h for passenger cars and above 70 km/h for heavy trucks. Research has been carried out during the last thirty years in order to understand and quantify the generation mechanisms responsible for tyre/road noise. READ MORE

  4. 4. Online and Offline Identification of Tyre Model Parameters

    Author : Anton Albinsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; state estimation; computer aided engineering; tyre testing; parameter estimation; tyre-road friction estimation; active safety; simulation; vehicle dynamics;

    Abstract : The accelerating development of active safety system and autonomous vehicles put higher requirements on both environmental sensing and vehicle state estimation as well as virtual verification of these systems. The tyres are relevant in this context due to the considerable influence of the tyres on the vehicle motion and the performance boundaries set by the tyres. READ MORE

  5. 5. Modelling of Dynamic Contact - Exemplified on the Tyre/Road Interaction

    Author : Krister Larsson; Chalmers University of Technology; []
    Keywords : tyre dynamics; rolling noise; rolling contact; dynamic contact; tyre road noise; tyre road interaction;

    Abstract : Noise is a severe problem in modern society. Road traffic noise is a substantial contributor and the tyre/road interaction is the main noise source for normal driving conditions. Despite more than 30 years of research, there is a lack of quantitative tyre/road noise prediction models. READ MORE
